booting a diskless motherboard via ethernet?

Post by Tero Laakkon » Fri, 15 Oct 1993 22:50:25


i have an extra 386 motherboard lying around and was thinking of
connecting it to my 486 via ethernet. i don't feel like snarfing a hard
disk or floppy thingy from my 486 setup for booting, instead i wanna boot
via ethernet. just like booting a X-terminal, i understand.

i was under the impression that i had to replace my 386 motherboard
boot rom so that it would know that it has to go looking for boot code
from the net (as well as "a:" and "c:").

i marched to the computer store and asked the dude if he had such boot
roms, and he said that i don't need one."it looks for boot code in a:
and c:, and if they don't exist and a WD or whatever exists, it
transfers control to the boot rom in the WD" he claimed.

is this true? doesn't this imply that all i have to do is install some WD's
and make sure bootd and stuff are running and perhaps patch the kernel
somewhat and "we have lift-off"? my 386 motherboard has a bios dated
1989, is it even capable of the above netboot trickery?

sounds much too easy. correct me if i'm wrong.



1. booting diskless via SRM?


Is it possilbe to boot Linux (Redhat 5.2, but I could upgrade to anything
that would be required if necessary) on a diskless UDB/Multia via the SRM
console? I need some sort of boot block that can be sent via tftp to the
multia and that will then either load MILO or the kernel. I tried to directly
sending the kernel via tftp, but of course it did not work.

Any hints would be appreciated. Currently I am loading MILO from the floppy
via ARC, and MILO than loads the kernel via NFS, but I don't really like this

Kind Regards,
